Title: Dynamics of binary quantum mixtures

Abstract: We employ time-dependent density functional theory and atomic orbital approach to study dynamics of binary, repulsive quantum gases undergoing a phase separation [1,2]. With our methods, we reproduce recent experimental data in both Fermi-Fermi [3] and Bose-Fermi mixtures [4]. By combining classical fields description of bosons and hydrodynamic model of fermions, we provide a reliable framework which allows us to investigate a finite temperature dynamics of a BEC immersed in a polarized Fermi gas. As an additional treat, an aesthetically appealing result will be presented – the fermionic quantum carpet [5,6].
